Unlikely — Zone Mismatch
Oregon white oak (zones 5-8) does not overlap with North Dakota's zone range (3b-4b). Growing outdoors is unlikely without significant protection.
Your yard isn't the whole zone.
North Dakota spans zones 3b-4b, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score oregon white oak against your parcel's actual hardiness, soil, and sun.

When to Plant Oregon White Oak in North Dakota
The frost window
Across North Dakota, the last spring hard freeze (28°F) clears between Apr 30 and May 6, and the first fall hard freeze lands between Oct 4 and Oct 9 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 151-day window you can count on — up to 162 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
North Dakota runs as cold as USDA zone 3, and no sourced winter-hardiness floor is on record for oregon white oak, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether oregon white oak is a permanent planting or a replant-every-spring crop for you turns on your own zone within North Dakota; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says oregon white oak does not survive a North Dakota winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on North Dakota under protection.
Chill hours
Oregon White Oak requires ~800 chill hours (32-45°F dormancy window). North Dakota typically banks ~2500 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Oregon White Oak likes near-neutral soil (pH 5-7). That's the common-ground band across North Dakota's prairie loam and clay (red river valley) — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 5.5 and 6.5 — worth knowing before you decide whether a North Dakota soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your North Dakota site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Oregon White Oak in North Dakota
Zone compatibility tells you about winter cold survival — but North Dakota growers also need to think about:
Extreme cold (-40F) and short growing season
Persistent wind desiccates plants
Low rainfall in western ND
What to actually do about these — and the constraints that apply to every North Dakota grower, not just oregon white oak — is covered on the North Dakota growing guide.
Where in North Dakota Oregon White Oak Is Zone-Hardy
Oregon White Oak is rated for USDA zones 5–8. No North Dakota county reaches it. Even Stutsman County, the state’s mildest winter at zone 4b, sits below the plant’s zone 5 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
Across those 53 counties North Dakota’s winter-low ladder runs from zone 3b in Bottineau County to zone 4b in Stutsman County — 1 USDA zone of spread, which is 10°F between the two counties’ average coldest night of the year. None of that range reaches the band oregon white oak needs, so here the statewide answer really is the answer.

Is Oregon White Oak native to North Dakota?
Oregon White Oak is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in North Dakota. It can still earn a place in a North Dakota garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Oregon White Oak in North Dakota
When can I plant Oregon White Oak in North Dakota?
North Dakota's last spring hard freeze (28°F) clears between Apr 30 and May 6, and the first fall hard freeze lands between Oct 4 and Oct 9 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Oregon White Oak, so this page does not state whether it overwinters in North Dakota and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Oregon White Oak grown in across North Dakota?
North Dakota spans USDA hardiness zones 3b-4b (USDA ARS PHZM 2023). Oregon White Oak carries a range of zones 5-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical North Dakota site have?
A typical North Dakota site sees ~157 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Oregon White Oak should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Oregon White Oak native to North Dakota?
Oregon White Oak is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in North Dakota. It can still earn a place in a North Dakota garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Oregon White Oak in North Dakota?
Oregon White Oak prefers pH 5-7 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across North Dakota soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Oregon White Oak actually grow on my specific land in North Dakota?
